Android developer with a background in industrial automation. Since 2021 I've been designing and shipping mobile applications — before that, I was wiring PLCs and building IoT systems for real factories.
From industrial automation to Android development.
I hold a Master's degree in Automation & Industrial Computing. During my final year, I built an IoT solar-energy monitoring system at Algeria's Renewable Energy Development Center (CDER) — acquiring sensor data and building a real-time Android interface to visualize it. That project convinced me that the most interesting problems live at the intersection of hardware and software.
Since 2021, I've worked as a freelance Android developer, designing and shipping custom applications for clients across different platforms — including apps published on Google Play. NexisCodeLabs grew out of that work: a small studio built around tools that actually hold up in daily, real-world use.
Tools I reach for.
Programming
Industrial & Control
Connected Systems
Tools & Workflow
A few milestones.
NexisCodeLabs
Built and published Stokko and EnergyZ on Google Play. Growing a small independent studio around Android tools that hold up in real daily use.
Freelance Android Developer
Designing and shipping custom Android applications for clients across freelance platforms, from first concept to a published app.
Final-Year Internship — CDER
Centre de Développement des Énergies Renouvelables, Algeria. Designed an IoT solar-energy monitoring system: sensor acquisition, signal processing, and a real-time Android interface for control and visualization.
Master's Degree — Automation & Industrial Computing
PID regulation, Grafcet, ladder logic, PLC programming, and industrial supervision — the foundation that still shapes how I approach software today.
Things I've built.
Stokko
LiveInventory management and POS system for Algerian retail — barcode scanning, stock alerts, debt books, and cloud sync, built for shops that need it to work offline first.
EnergyZ
4.8★ Play StoreBattery health and charging monitor using native Android APIs — real-time voltage, current, and performance tracking with alerts.
Solar IoT Monitoring
Case studyAn IoT supervision system for solar energy performance, built during my final-year internship at CDER — sensor data acquisition paired with a real-time Android control interface.
Vocalify
Coming soonFast, offline-ready text-to-speech conversion using native Android TTS engines — lightweight and distraction-free.
Let's build something.
Available for freelance Android projects and technical collaborations.
